zno nanostructures of different methods and sizes were grown in a controlled manner using a simple hydrothermal and sonochemical technique. controlling the content of concentration and temperature of the reaction mixture, spherical nanoparticles zno structures could be synthesized at temperatures 100-150 °c with excellent reproducibility in solvothermal and at different power and time in sonoch...

according to gas development in most provinces in recent years and the expansion of gas transfer pipeline in parallel, paying attention to project supply chains and related risks is necessary more than past. due to specific structure of project supply chain based on government regulations, this article is aimed at presenting a model to mitigate risks on projects supply chain in state gas compan...

the aim of the current study was to evaluate the replacement effect of soybean meal (sbm) at different levels (0 as d1, 33 as d2, 67 as d3 and 100% as d4 based on crude protein (cp) content) by guar meal (gm) on ruminal gas production kinetics, ruminal digestibility and fermentation characteristics of a fattening diet for lambs. three experiments were conducted. the first experiment of 144-h in...

The Great Salt Plains of Oklahoma (GSP) is an extreme region, a hypersaline environment from marine origin and a unique area of the Salt National Wild Refuge in the north-central region of Oklahoma. In this study we analyzed the diversity and distribution of bacteria in two habitats; vegetated areas (GAB) and salt flat areas (GAS) in the sediments of GSP using the high-throughput techniques of ...

The halothane muscle/gas partition coefficients at 37 degrees C for 26 samples of eight different muscles from four horses were found to depend significantly on the fat content of the muscle sample with a regression coefficient of 1.913 (SEM 0.109) per per cent ether-extractable fat content. The blood/gas partition coefficients in 24 horses showed a significant dependence on plasma triglyceride...

Perovskite-type N-substituted SrTiO3 thin films with a preferential (001) orientation were grown by pulsed laser deposition on (001)-oriented MgO and LaAlO3 substrates. Application of N2 or ammonia using a synchronized reactive gas pulse produces SrTiO3-x:Nx films with a nitrogen content of up to 4.1 at.% if prepared with the NH3 gas pulse at a substrate temperature of 720 °C. Incorporating nit...

The variation in the content of extractives from Eucalyptus globulus wood has been studied during a three-month seasoning experiment. The decrease in the total acetone extract (by over 56%) after seasoning is well correlated to a parallel reduction on the colloidal pitch measured in black liquors. The composition of lipophilic extractives during the seasoning period has been studied by gas chro...

A low SV causes relatively slow pyrolysis conditions at around 600°C, and produces high yields of charcoal 20-30%, large quantities of unburned tars, and a gas with high hydrocarbon content and high tar (volatile) content. A high SV causes very fast pyrolysis, producing less than 10% char-ash at 1050 C and hot gases at 1200-1400 C in the flaming pyrolysis zone. These gases then react with the r...

We have observed 70 galaxies belonging to 45 Hickson compact groups in the CO(1→0) and CO(2→1) lines, in order to determine their molecular content. We detected 57 galaxies, corresponding to a detection rate of 81%. We compare the gas content relative to blue and LFIR luminosities of galaxies in compact groups with respect to other samples in the literature, including various environments and m...
